Start with the documented color character
First Star is a cool gray-white with more depth than a very bright white. Temperature is a useful description, but neighboring materials can change the impression. First Star is deep enough to be a gray-white rather than one of the highest-reflectance whites.
Why the white doors and silver-gray tile relationship matters
White doors offer a stable comparison for deciding whether the gentle gray boundary is visible enough from the entrance.
First Star has an LRV of 69; Sherwin-Williams Eider White SW-7014 is 73. The difference is 4 points, with Eider White returning more light under the reference measurement. Eider White is a cool white softened by gray. This supplies a named color control; the LRV gap alone does not identify the warmer, greener or pinker paint.
Use Eider White as a control
Put First Star directly against the whitest permanent surface and then against the warmest one. If those two boundaries disagree, decide which surface controls the project. The word warm cannot reconcile every ivory cabinet with every white stone, and a cooler label does not automatically imply an unsuitable room.
Separate a persistent cast from a comparison effect
View the wall and doors from the room entrance; keep First Star if the gentle separation is sufficient. The undertones and neighboring colors covers that related choice.
Judge the temperature description against the full white doors and silver-gray tile arrangement. A warm or cool label is a useful starting category; it cannot guarantee that First Star agrees with every material assigned the same label. The wood-floor pairing guide covers that related choice. Before ordering samples, compare room-planning features in the paint color visualizer roundup.
